At Big Blue Saw galactic headquarters, we have a number of recessed ceiling lights that have sprouted high efficiency CFL bulbs. They produce plenty of bright light, helpful in the dark winter months. The downside is that they look kind of ugly. See for yourself in the photo below.
I had the idea to make these a bit prettier by making a cover. But why make a plain lighting diffuser when I could use the laser cutter to make them Big Blue Saw themed! I designed a 10 inch diameter diffuser with a series of 5 mounting holes the at the same diameter as the recessed lighting fixture ring.
For the material, I chose our stock P95 acrylic, which is ideal for a lighting fixture as it transmits 95% of light and diffuses light in a soft pattern. After laser cutting and removing the protective paper coating, we had the piece shown below.
To install these, I used some clips made from copper wire. The diffusers were installed frosted side up. Here are the results.
Much better. I especially like the way the edges catch the light. What do you think? Let us know in the comments.
